3 @laims. (Cl. Elli-Jill) lhis invention relates to well tools andequipment and it has particular referenceto a combined rod hanger andtubing rack forwell derricks.

The principal object of the invention is to provide an economicallyelficient and safe means for suspending and retaining sucker rods in thederrick whereby the disadvantages present in the customary handling ofrods is overcome as well as the accidents resulting from accidentalrelease of the rods, which frequently causes injury to workmen on thederrick floor.

Another object of the invention is to provide a rod hanger which ispivotally displaceable relative to the point of operation on the derrickfloor in order that the rods, when pulled and suspended may be moved outof the way so that the operation of pulling tubing may be carried onwithout interference.

Another object of theinvention is to provide a new and novelg-rapplingand hoisting means which lends materially to the ease andreadiness by which the rods may be brought to rest inthe hanger by anattendant as well as positively preventing accidental release of the rodwhile the same is being placed in the hanger.

Another object of the invention is to provide in combination with therod hanger, a platform serving as a tubing rack and which platform isadjustable relative to the rod hanger as well as other points ofoperation on the derrick floor, such adjustments being advantageous asregards both the platform and the rod hanger since operations may becarried on on either side of the central point of the derrick dependingupon wind and weather conditions and the like. Both the tubing rack androd hanger may be moved out of the way of operation at any time desiredand locked against accidental displacement from any position to whichthey may be moved.

With the foregoing objects as paramount, the invention has particularreference to its salient features of construction and arrangement ofparts, which will become manifest as the description proceeds; taken inconnection with the accompanying drawings, in which:-

Continuing with a more detailed description of the drawings, referenceis primarily made to Figure 1 wherein l designates the leg of aconventional steel derrick, the braces and girts being designated by thereference character 2. First, the bolts 3 shown in Figure 13 are removed'pr'eparatory to mounting the brackets 4 which serve to support theinvention at a convenient location above the derrick floor 5. It isapparent that by removing the bolts 3, the derrick is not weakened atany point while the brackets-4 are being aplid plied. The brackets lcorrespond inshape to the angle of the leg I and therefore conformablyfit.

.The upper bracket 4 is held in position bybolts 6 while the lowerbracket is secured by means of of which are aflixed to a pintle or blockIII which is disposed in the recess position of the bracket 4 andpivotally held therein by a pin II. The confronting edges a of themembers 9 are beveled as shown particularly in Figure '7 and these edgesconform with the annular V-shape groove in a roller I2 which is mountedon a roller hearing I3. The shaft I4 on which the bearing I3 is mountedextends through the walls of a member IS, the latter being comprised ofrelatively spaced parallel members embracing the members 9. The outerends of the members comprising the member I5 are joined together by aplate I6 as shown in Figure 1 and held in fixed relationship by pins orbolts IT.

The shaft I8 is carried by the free end of the member 9 as shown indetail in Figure 8 and each end of this shaft carries a roller l9 havinga V- shaped annular groove therein to conform with the beveledconfronting edges b of the members comprising the member I5. It isapparent from the foregoing that the arrangement provides for slidingmovement of the member I5 upon the member 9 and which enables itsoperator or attendant to properly adjust the member i5 which is the rodhanger relative to the point of operations, thereby making it convenientto properly dispose the rods in their respective retainers.

The rod retainers are constructed in the manner shown in Figures 2 and3, each being formed of a substantially circular casting 20, each havinga recess breaking the continuity of the circle and they are furtherprovided with a stationery gripping member or slip 2| and a removableslip 22. A dove-tailed projection 23 is provided on each retainer 20 tobe conformably received by recesses 24 on each of the members comprisingthe rack I5. The retainers 20 are also provided with recesses 25 on oneside, the purpose of which is shown in Figure 3, i. e. to provide meansfor receiving and holding the removable slip 22 in a position accessibleto the operator or attendant.

The member 9, as shown in Figure 6, has an opening 26 therein to receivea wedge shaped pin 21, thepin being held in the opening by a key 28connected to the endof the pin by a chain 29 to prevent loss thereof.Asupporting cable 30 is connected to the pin 21 and extends to the topof the derrick or to some suitable point in the derrick to carry theweight of the rod hanger and its load of rods. An eyelet 3|, shown onlyin Figure 1 is provided, to which is connected a cable for the purposeof raising the rod hanger to a position to be mounted.

The outer end of the member 9 supports an upright 32 and pivoted to thetop of this upright by means of a bolt 33 is an arm or crane 34.Referring to Figure 10, a grooved roller 35 is mounted in either end ofthe arm 34 and a cable 36 is passed over these rollers and lies within agroove 31 in the arm 34. The cable 36 continues over a roller 38 mountedin the upright 32 and downward through an aperture in a lever 39. Aseries of stops 40 are provided in spaced relationship on the cable 36and are shaped to conform to the shape of the aperture in the lever 39so that they will not pass through the aperture.

Through this arrangement, the cable 36 may be lengthened or shortened asdesired.

Suspended from the other end of the cable 36 is a grapple or elevator4|. This elevator-is shown in Figures 14 and 15 in detail and iscomprised of a bifurcated member 42 having mounted therein a groovedmember 43, the latter being pivoted at.44. A shoulder 45 is provided onthe wings of the member 43, for a purpose to be explained later.Normally, the elevator is in the position shown in Figure 15 and when itis desired to engage a rod 46, the body 42 is pivoted to the positionshown in Figure 14, in which position the squared end of the sucker rod46 may be readily inserted into the recess of the member 43, theshoulders 45 serving to prevent release of Lie rod and the weight of thelatter will cause the body 42 to move into the upright position shown inFigure 15, in which position, the rod 46 is positively locked againstescape or accidental release from the member 43. The pivotal point ofthe member 43 at 44 is offset relative to the connection of the cable 36with the body 42 and this fact is a further insurance that the rod 46will not be released from the elevator until the rod has been movedthrough the opening 0 of the retainer 20 and secured by the slip 22.After having been thus secured, the body 42 is manually returned to theposition shown in Figure 14 and the elevator may be readily removed fromthe rod 46.

As the rods are elevated or withdrawn from the well to a position forreception by the elevator 4|, it is desired that the cable 36 be securedagainst movement. A locking means for this purpose is shown in Figure 6and is comprised of an eccentric 41 pivoted at 48. A lever 49 isprovided to actuate the eccentric 41 so that it will bear against thecable 36 and urge the latter against the periphery of the roller 38 witha wedging action. The greater the pull upon the cable 36, by the weightof a rod or the like, the more secure the locking means. Downwardpressure upon the lever 39 will relieve the wedging action on the cable36 and release the eccentric 31 to the action of the spring 50. Thecrane may be .then manipulated by the lever 39 to bring the suspendedrod into proper position for reception by a selected one of the severalrod retainers 20.

The fact that the rod hanger is movable orlongitudinally adjustable,allows the operator to change the position of the retainers 20 at willto render less burdensome the work of mounting the rods in theirrespective places in the hanger.

As a means for supporting the attendant or operator during the operationof pulling and 5115- pending the rods, a platform isprovided and whichserves also as a tubing rack. This device I is comprised ofasubstantially rectangular member whose normally operative position isshown in dotted lines in Figure and has a series of recesses 52- in oneside thereof to receive sections of tubing. The member 5| is pivoted at53 to an outwardly extending arm 54. This is shown in detail in Figure 9as well as in Figure 1.

The arm 54 has an enlarged end or pintle 55 which is received in therecess of the lower bracket 4 and pivotally held therein by a pin 56.The pivotal relationship of the arm 54 with the bracket 4 allows theformer to be moved to any position desired. As a means for looking ortemporarily holding the platform 5| in adjusted position, a corrugatedboss 51 is provided on the pintle 55 of the arm 54 which correspondswith the opposite side of the point of operation. These 7 a similar boss58 on the bracket 4 as shown in Figures 4 and 5. In addition tothistemporary of the arm 541s beveled at d. This feature all--- lows theplatform 5| to be tilted as shown in dotted lines so that it may be morereadily rtated to adjusted position relative to the supporting arm 54.

While rods are being handled on one side of the point of operations, theplatform is shown properly adjusted in Figure l and secured by means ofa boltBl'L Apertures 6| are provided at four corners of the platform sothat the latter may be reversed in its position relative to the arm 54should the operations be carried out on features. of adjustment arelikewise important when the platform is loaded with tubing and movedaside out of the way against one side of thederrick in the manner shownin Figure 10.

It is of course preferred that the platform or tubing rack lie flushagainst the side of the derrick as illustrated both in solidlines and indotted lines in Figure 10, depending upon which side of the point, ofoperation the work of loading the rack is carried out.

In Figure 12 is shown a detail fragmentary.

view of the platform or tubing rack 5| in order to illustrate a stop orguide 62. The guide 62 slides within a dove-tailed recess 63 and may besecured in adjusted positions by virtue of apertures 64 into registerwith which is moved an aperture 65 in the guide arm 62.. A suitable pinor bolt inserted in the apertures will hold the arm 62 againstlongitudinal -movement. The outer end of the arm 62 is concave at 66 sothat a section of tubing may be rested thereagainst A ring 61 isprovided midway between the ends of the platform for the purpose ofreceiving a cable by which the platform is elevated to a point in-thederrick for mounting and in addition, a pair of hooks 58 are provided onone side of the platform adapted to engage over the girt 2 of thederrick to hold the platform against release when in the-inoperativeposition shown in Figure 10.

As a means for holding the sections of tubing within the recesses 52 ofthe platform 5|, ap-

ertures 69 are provided therein between the recesses 52 through which arod is passed.
